As the vibrant blooms of summer fade and winter approaches, many gardeners wonder whether they should cut down their hydrangeas for the colder months. The answer depends on the type of hydrangea you have and your local climate. Let’s explore the best practices for preparing your hydrangeas for winter to ensure they come back healthy and strong next spring.


Understanding Hydrangea Types

Different hydrangea species have varying requirements for winter pruning. Here’s a quick guide to the most common types:

1. Bigleaf Hydrangea (Hydrangea macrophylla)

  • Winter Pruning: Bigleaf hydrangeas bloom on old wood, meaning they develop flower buds for the next year on the previous season’s growth.
  • Recommendation: Do not cut these hydrangeas down to the ground in winter. Only remove dead, damaged, or diseased wood after the plant has bloomed in late summer.

2. Panicle Hydrangea (Hydrangea paniculata)

  • Winter Pruning: Panicle hydrangeas bloom on new wood, meaning they produce flowers on the current season’s growth.
  • Recommendation: These hydrangeas can be pruned in late winter or early spring before new growth begins. Cutting them down to the ground is not necessary, but you can prune them back to shape and control their size.

3. Smooth Hydrangea (Hydrangea arborescens)

  • Winter Pruning: Smooth hydrangeas also bloom on new wood.
  • Recommendation: Prune these hydrangeas back to about 6-12 inches from the ground in late winter or early spring. This encourages vigorous new growth and large blooms.

4. Oakleaf Hydrangea (Hydrangea quercifolia)

  • Winter Pruning: Oakleaf hydrangeas bloom on old wood.
  • Recommendation: Avoid cutting these hydrangeas down in winter. Prune only to remove dead or damaged wood and shape the plant after it blooms in summer.


Preparing Hydrangeas for Winter

In addition to knowing when and how to prune, there are other steps you can take to prepare your hydrangeas for winter:

1. Mulching

  • Why: Mulching helps protect the roots from temperature fluctuations and retains moisture.
  • How: Apply a 2-3 inch layer of mulch around the base of the plant, keeping it a few inches away from the stems to prevent rot.

2. Watering

  • Why: Proper hydration is crucial before the ground freezes.
  • How: Give your hydrangeas a deep watering in late fall to ensure they have enough moisture going into winter.

3. Protecting

  • Why: Harsh winter winds and ice can damage hydrangea stems and buds.
  • How: For more delicate varieties like Bigleaf hydrangeas, consider creating a windbreak with burlap or wrapping the plant loosely with burlap to protect it from drying winds.


Common Winter Care Questions

Q: Can I cut my hydrangeas down to the ground?

  • A: Only Smooth hydrangeas benefit from being cut back to the ground in late winter or early spring. Other types should not be cut down completely, as this can reduce or eliminate blooming.

Q: What happens if I prune at the wrong time?

  • A: Pruning at the wrong time, especially for old wood bloomers like Bigleaf and Oakleaf hydrangeas, can remove the buds for next year’s flowers, resulting in little to no blooms.

Q: How do I know if a stem is dead or alive?

  • A: Scrape a small section of the bark with your fingernail. If you see green underneath, the stem is alive. Brown indicates it is dead and can be pruned away.



Knowing whether to cut down your hydrangeas for winter depends on the type you have and their blooming cycle. By following the guidelines for each hydrangea species and preparing them properly for winter, you can ensure a beautiful and healthy display of blooms next season.
